3 Claims.

This invention relates to egg boxes or carriers of the type having anouter casing or wrapper and an inner liller made up of longitudinal andcross strips having interlocking slots by which the strips are connectedto form cells. The invention is concerned principally With simple meansfor eliectively securing the filler in the casing so that these partsmay be shipped in collapsed condition and easily assembled to form thecomplete box by inserting the filler in the casing when the box is to beprepared for use. Other improved details -of structure are alsocontemplated as will later appear.

The invention is illustrated in the accompanying drawing, forming a parthereof, in which Figure 1 is a vertical transverse section of a boxinvolving the invention;

Figure 2 is a horizontal section on the line 2 2 of Figure 1;

Figure 3 is a partial vertical section on the line 3-3 of Figure 1;

Figure 4 is a perspective view of a complete box with parts broken away;and

Figure 5 is an enlarged perspective view of certain parts showingparticularly the means for attaching the ller to the casing of the box.

Referring to the drawing in detail by the reference characters thereon,the casing or wrapper includes a bottom portion II), side wall portionsII and cover portions I2, the latter along their free edges beingprovided with truck-in naps I3.

The ller is made up of a plurality of spaced longitudinal strips I5 anda plurality of similarly spaced cross strips I6, these strips formingthe cells. The strips I5 and I6 are provided with interengaging slotspreferably of the kind disclosed in U. S. Patent No. 1,140,643. Theslots I5A in the strips I5 are curved in shape and on one side thereof alocking lug I5B is formed having a square shoulder. The slots in thestrips I6 comprise an outer slot IGA and an inner aligned slot IBB. Whenthe strips I5 and I6 are assembled to form the filler, the lugs I5B onthe former engage in the inner slots IBB of the latter and thereby thestrips are locked together to form the filler, as fully set forth insaid patent.

The means for securing the ller in the casing may now be described. Thelongitudinal strip I5 on each side of the filler is arranged relativelyclose to the corresponding side wall Il of the casing. These sides II ofthe casing are each cut away at several points to form wings IIA whichare bent inwardly of the casing and these wings are so spaced that whenthe filler 1s 1nserted in the casing the wings IIA will 11e flat againstthe cross strips I6 and will extend across or intersect the adjacentlongitudinal strips I5 of the ller. One or more of these wings IIA areformed on each side II of the casing. The wings are each provided withvertical interlocking slots I IB, I IC substantially like and arrangedto register with the slots IGA, IBB in the cross strips I6. When thewings I IA are bent inwardly at right angles to the sides II, it will beseen that a filler composed of the strips I5 and IB can then be forceddown into the casing and the longitudinal strips I5 adjacent the sidesII will interlock with the wings I IA in the same manner that saidstrips interlock with the cross strips I6. The ller will thus be firmlylocked in the casing by engagement between the wings Il of the casingand the longitudinal side strips I5 of the iiller.

The fillers and casings may obviously be shipped in a separated orknock-down condition and when they are to be used for packing the eggs,a filler is assembled with a casing by first bending the wings IIAinwardly and then forcing the filler down in the casing to lock theparts together. The cover portions I2 of the casing can thenbe bent downto form a complete cover for the box, the truck-in iiaps I3 beinginserted in the upper ends of the slots IBA formed in the center of thecross strips I6, these slots being made of a Width to tightly receivethe flaps.

What I claim as my invention is:

y 1. An egg box comprising, in combination, a casing having a bottom andspaced side walls, a filler for said casing having spaced longitudinalstrips and spaced cross strips arranged at right angles to each other toform cells, said strips at their points of crossing having interlockingslots formed therein, the longitudinal strips at each side of the fillerbeing arranged in close proximity to the corresponding side Wall of thecasing, said side walls of the casing having Wings formed thereon andextending inwardly therefrom and intersecting the adjacent side Wall ofthe filler, each of said wings being arranged adjacent to and parallelwith one of said cross strips and having a slot therein corresponding toand arranged to register with the slot in the adjacent cross strip andmeans in said registering having wings projecting inwardly therefromtransversely of the adjacent longitudinal strips of the'ller, each ofsaid wings being positioned adjacent to and parallel with one of saidcross strips of the ller, said cross strips and said wings havingvertical locking slots formed therein arranged to register with eachother, said intersecting longitudinal strips also having verticallocking slots formed therein arranged to engage and interlock with theslots in said wings and cross strips, to thereby lock the filler in thecasing.

3. In an egg box, in combination, a ller having spaced longitudinal sidestrips and a longitudinal center strip and also spaced cross strips, acasing in which said filler is mounted, said casing having a bottomportion, and side walls, each of the side Walls of said casing havingwings formed thereon extending inwardly therefrom and intersecting theadjacent longitudinal side strip in the filler, each of said wings beingpositioned adjacent to one of said cross strips and vsaid wings and theadjacent cross strip having vertical interlocking slots thereinregistering with each other, said longitudinal side strips also havingvertical slots formed therein arranged to engage and interlock with theslots in said wings and cross strips to thereby lock the ller in thecasing, said longitudinal center strip and said cross strip also havnginterlocking slots therein, said casing also having a cover portionextending inwardly from the top of each of said side walls, each of saidcover portions having a tuck-in portion along the edge thereof adaptedtoy be insertedin the slots of said cross strips adjacent saidlongitudinal center strip.
